Would you judge someone for modifying their Merc/Bimmer/Lexus/Infiniti/Lincoln/Audi/Cadi like a 240SX for performance?
A new luxury car, you mean? Seems rather an odd choice to take a luxury car and deliberately remove the luxury that is one of its selling points. Why not buy something without any of that, which is probably a better platform for modification anyway, for less money?
Obviously e36s and is300s and shit make fine, cost-effective platforms for tuning, but I assume you aren't talking about stuff like that.
Cool if you do it like this
You have the means and space to build something good, why are you wasting your time on these cars? You don't have to be married to them just because you already dumped a ton of money into them, it's not too late.
Anyone can make a sports car faster, I enjoy this rather. If you lose to a Viper or something of the sort, who cares? It's meant to be fast. I'm manual swapping the GS, waiting for Collins to send everything out. Just a different sense of gratification man. Each to their own
