@Tibbs - Chris above is right though. You can get slow cars that are cool in their own way and people accept that. Spending hard earned on making a basic, near 23-year-old car 'sound nice' is just a waste.
You might as well stick an AMG badge on the back for all the relevance it will have. As Chris said - not wanting to sound harsh, but at best, you'll get nothing other than dubious glances.
It's just gonna be a fun little car I'm not trying to make it brake any records just want it to sound nice look alright and if I get the use I will eventually upgrade to something different
