Well basically you're buying the engine, for around the same price I can try to find a c63, gran tourismo. I dunno if isf is too old. I've never driven one but I've driven is350. 300hp was real fast at the time as a learner. And seems more tame compared to the others. Quattroporte seems to be over priced for what people want for them, they get into gran tourismo money. I'm not sure how horrible the V6 V8 stellantis quattroportes are cuz they are retarded cheap like used golf r money. $2-30000. Less than a used Rc. I skimmed last night and people are asking $50000 for a used none f rc
