Hey All- Relatively new here. I have a 2015 M235 and am thinking about doing some mods- Dinan performance tuner stage 2 and cold air intake. I'm wondering how that might affect resale value? Is the car worth more? Less? No difference? Anyone have experience with that? Thanks!

[RoundelM3]

No difference when trading it in, and up to the buyer when selling privately. Best recommendation is to remove the items and sell them separately if you're trading or the buyer doesn't care about them. My previous car had full Dinan S3 equipment (tune, FMIC, oil cooler, CAI, and exhaust), and I was able to sell it to a fellow BMW CCA member who appreciated the extra equipment and power it produced. Dealer said the average customer didn't care about that sort of thing and that it would not add any value to the car.

I sold the stage 3 dinantronics for m235 for 600$.
It has no value for resale since the "warranty" does not carry over.


Typically mods are not worth anything on the resale value of a car.

It makes me laugh when you see a 335 thats worth 18k being sold for 65k because they put every go fast mod on it.
It doesn't work that way.

I would leave the parts on, and try for a private sale first. If thats taking too long, take the parts off and sell them by themselfs for a fraction of original cost.

Honestly some buyers in the used market prefer stock cars due to less abuse on the mechanicals. Logic is engine at lower boost, for example, probably less likely to have failure in future.

The one exception that that may be non-warrantied items such as the relatively new Dinantronics Sportronics piggyback. It's sold based on series, not engine type, which is part of the design -- it senses the car it's installed on and loads the appropriate map. That makes it easily transferrable from car to car ... and part of the reason I'm about the take the plunge on one (hey Evan@Tischer and Jason@Tischer : got a PM to y'all about it!)

I agree. When I traded in my low mileage 2004 Mazda RX-8 on my M235i, the dealer had a difficult time containing his enthusiasm for my trade-in. It was well maintained (OEM parts only), clean, damage-free and mod-free. As a result, he offered me good trade value for the car, even though it was almost 10 years old.

Another aspect to consider is that for those with the mod bug, much of the fun is doing it yourself exactly the way you want. Best to get a good low mileage stock car as a blank canvas.

Obvious mods make your trade in worth less unless they are M Performance parts. Otherwise the dealer has to remove them to CPO the vehicle.

[Maynard]

In resale land, mods often signify hard use, and will probably drive the price down unless it is a fellow gearhead. No doubt this is unfairly channeling that 'drive it like you stole it - Gone in 60 seconds' vibe, but you can't really make a case that having a Dinan piggyback actually HELPED your engine longevity, can you? Now if you also kept nice records of every meticulous service and fluid change, THAT will boost value, as it shows a well-cared for car (just lose the receipts for all those hi-po mods). I doubt a dealership could/would actually resell it with the Dinan in place, so talking to them about it seems especially unrewarding and prone to cause problems.

This is true I had my Dinan done at a BMW dealer and to CPO the car for me they have to remove it, CPO it, then put it back on.

The sport is not even considered during my post due to it only providing 10whp.

You are better of going with the JB+ if yu want a simple to plugin, take out solution, and its 100$ cheaper.

First: Let's not devolve this thread into something it shouldn't be. I merely posited that the Sportronics could be an exception because it can easily be sold independent of the car.

But if you insist ...

Second: you're wrong.
Exhibit A: Here is Dinan's gains chart on an otherwise stock 228i N20.
Exhibit B: Here's is a post by someone who compared the BMS Stage 1 to the Dinantronics Sport on an otherwise stock 328i N20. He tested them back-to-back on a Dynojet 428 dyno. Here is the entire thread.

At minimum, the Dinantronics Sport provides 24 HP and 34 ft-lbs more than stock by itself on an N20. At minimum. By comparison, Exhibit C: Burger Tuning's chart of its JB+ on an otherwise stock 328i. The gains are almost exactly the same: 24 HP and 33.5 ft-lbs.

Lastly: I don't (and many others don't) care for the solution that produces the most gains. That Dinan backs up most of its other products up with a warranty is good enough for me regarding reliability. My car is under factory warranty. I want it to stay that way. Plenty of others want that, too -- and for those, a JB+ or JB4 is not a viable option.

Carry on.

First chart is Crank HP, not wheel.

Second chart is with a BMS intake. So i stand by my 10whp number still.

Hope you enjoy it!

So is the baseline, so your argument is not valid.

Yeah, riiiiight. Nice try.

See the info I just added to my post about BMS' JB+ for the N20 -- taken on a Dynojet dyno. Again: baseline.

Furthermore, it's been well established in multiple threads that an intake on an N20 does virtually nothing gains-wise until at least Stage 2. If you would like, I'll happily supply links to some of those threads ... but I really don't think I need to bother at this point.

Look: Some may prefer BMS' top-heavy peaks vs. Dinan's more plateau-like mapping. I get that. But when it comes to these one-sensor piggybacks, that's the big difference: not power/torque gains. I'll gladly pay a premium for Dinan's track record vs. BMS'.

As for further argument ... you need to supply proof, as I have done. Otherwise, your argument's not valid.

[bryan_G01]

There is a reason why I threw out the stage 3 Dinan after spending 6g on it.
At this point, BMS has a better reputation than Dinan has espcially within the 2 series community.

Anyone who used a Dinan product and got rid of it will back my claim.

I'm still waiting after a year for them to RMA the camber plates they released than pulled off the market. Top notch warranty for sure.

I hope it delivers 100whp for you. Enjoy it.
Carry on.

I paid just over $4k (CAD) for my Stage 3 set up. I love my set up. I also have the sport Dinan on my n20 x3 and also love that tune.

Zero complaints and will always back my Dinan choices.

Thanks. I really didn't want this to devolve into yet another BMS-vs.-the-world thread. Good lord.

Still no proof other than what I supplied. Gotta love fanboys (especially ones with apparently all but unlimited funds ... and an N55 ... and who asked, in another thread, if he should hold off installing aforementioned camber plates -- and got an answer from Dinan saying yes, do not install; we've discovered a manufacturing defect -- not a year ago, but five months ago ... oh, and to whom Dinan is publicly acknowledging it owes.)

Truth. Some people are just impatient, bitter, and think their experience and everyone else's experience are one and the same.

[bryan_G01]

BMS Fanboys? I have a flash tune.

Thanks for pulling my history, if you applied that much effort to a career maybe you would have "apparently all but unlimited funds".

Have a nice day!

[allthatisntnow]

[wjjkoevoets]

Is this really necessary guys?

On-topic: IMHO the value of the car is unaffected or it's decreased. Unless you've got some unique set of mods that's really special I doubt you're gonna get anything out of it.

LOL! My life is not all about making money and going faster than the next dude ... and my career, of which quick and accurate research is a key component, is going just fine.

(Narrow minds and knee-jerk assumptions due to acute butt hurt tick me off.)

Happy belated Thanksgiving!

[CollegeParkM235]

thanks all for the responses. They all make sense in a way. One thing I wonder though- many BMW dealers sell and install Dinan, so for them to say it reduces value on trade in seems a bit ironic! I'm having mine installed at a dealer in VA next week, along with M performance exhaust. So at least that exhaust will add some resale value!

Oh, and for grins, I asked the sales manager about getting an M2. He said they have a list, no idea how long it would take, and $3k over sticker.
