Hey so I was hoping to possibly get some upgrades for my car in the future but I don’t really know where to start.

I was wondering if I could get a V6 or some real fast engine to fit. Then I’d get the Straight Piped to Silent Mod for the exhaust. I didn’t know if there was anything else I needed to add to make everything flow perfectly or that would drastically improve my speed and control.

I could also upgrade the whole interior to have very fancy digital gauges. Maybe something like this photo. While if by then we have an AI system that could act as a censor for the environment around me. Like if I’m changing lanes it’ll let me know if I’m good or whatever. It will also let me know if there are police nearby and how close they are getting so I can slow down if I need to. While I have very good racing tires and idk if they make them spike proof?

Any suggestions would be amazing just looking to make my car absolutely perfect. Otherwise I’m looking to maybe buy a late 1900s MGB or something that’s a sports car.
