Oh yes. I've played with cars for many years... I recently sold off a 2004 Porsche Cayenne turbo, 450hp. It was a pain on the maintenance end and just to replace a headliner with factory eqvt. fabric was $3,000! All because the headliner was starting to lose adhesion in the Florida heat. Plus it had some other issues, I had to do the cooling pipe repair after one of the sub-standard plastic pipes let loose at 61K miles and that was a pain. Friend of mine that's a line tech with Hyundai and I did the repair in my driveway over a weekend. Had to take the intake manifold clean off of the engine to access the pipes, it was in the valley of the motor where the work needed to be done. And we threw in a starter while it was open as the icky pink Porsche coolant saturated the original starter when the pipes went.
Quick story, it was so funny.... I was looking at a 2009 BMW 335D that CarMax in Sanford, FL had after I made the decision to get rid of the Porsche. The car was loaded and had low miles on it, paddle shifters, etc etc... it was advertised for around $24K. Anyway... I gave them the Porsche for an appraisal while I was out test driving the 335D.... After I drove it and brought the BMW back I walked over to the salesman's cubicle and sat down. The offer for trade-in from CarMax was $2,500. I laughed.... and laughed.... and told the salesman that the used car appraiser needed to be substance-abuse tested, got up and walked out. I sold the Porsche for $15,000 on private party sale a week later.
My daily driver is a 2011 Chevrolet Caprice PPV... rather rare car, not many in private ownership here in the US. I display it at car shows and yes, it's been modded. SLP Powerflo exhaust, Rotofab CAI, rear end ratio change from 2.92 to 3.45, street tune.... it'll chirp the 1-2, 2-3, and sometimes the 3-4 shift when I get into it. And.... I have NO personal knowledge the car will do 150 in 5th gear before it shifts into 6th....
