Everyone from Joel in sales to Zach in finance was amazing to work with. They made sure I understood and was comfortable every step of the process of buying our new car.

STUNNING MACHINE S5 Cabriolet

June 14, 2021
By S5LIcabrio from Long Island
Owns this car

I can write an entire diatribe about this car but I'll keep it simple! If you are looking for a luxury, convertible, look no further than the S5 cabriolet. I looked at the C43, M440i, this car, IMO, is the BEST value for the money! It is an absolute beast in the performance department, the options that come with this car for the price are unmatched and of course every single detail is perfectly executed!
