I bought the car with 2,000 miles on it from the dealer who sold it. The original owner decided it wasn't the car for them. Since then I have done all maintenance and services myself. I change oil every 5000 miles.
The AWRON gauge allows you to monitor most everything, - Voltage
- Water Temperature
- Oil Temperature
- Horsepower
- Torque
- Speedometer
- 0-60 mph & 0-120 mph Acceleration Timer
- Two Axis G-Meter
- Power and Torque Graph
- Fuel Pressure
- Intake Temperature (After Cooler)
- Exhaust Temperature (Modeled)
- Air Fuel Ratio (Before Catalytic Converter)
- Transmission Temperature
- Maximum Recorded Values
and a bunch other.
I do monitor oil pressure and temps to ensure nothing is wrong.
It only takes maybe a 1/2 hour to remove it and put the vent back in. I have all of the original parts except the intercooler as a small steel rod had penetrated it.

I will say I am having second thoughts about selling it as it has been the most dependable car I have ever owned and one of the best around around cars I have owned. I have had multiple BMWs, M3s, Z4m, 335, etc and also had a M-B sl65 AMG and I like this one the best but I have retired and really don't drive it much anymore as the mileage reflects.

I have no problems with someone coming and checking it out
