A must stop for Audi newbies
We had been searching causally for a few months for a plug in hybrid suv. We had toured a bunch of different brands and nothing felt right. We made an appt to see one at this dealership and we’re blown away. The team gave us our most in depth tour (over 2 hours ), helped us navigate finances and find the perfect vehicle. We loved working with Wesley and Jazmin. We’re based in the city, but found the dealership so easy to get to. As young professionals, this was our first big car purchase and know it won’t be out last with this team.
STUNNING MACHINE S5 Cabriolet
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!
