As Zedcat says, actual door-to-door racing is different than a DE, and requires a bunch of modifications. A car that has done regular Time Attack events or seen some serious autocrossing will have been subjected to more stress on certain components, but depending on the car it doesn't necessarily undermine the value. A significant percentage of GT3s see track time, for example, as do Cayman Rs. GT4s will almost certainly be tracked more than other Porsches, and a few events a year wouldn't be a cause for concern unless a buyer is looking for a garage queen.
I view "never..." statements in ads as a bit odd, as though they are testament to a car leading a "perfect" life.
Never seen rain? Ummm...ok, but what about salty ocean spray on a drive down the coast?
Never been smoked in? What about driving in the summer in an area close to forest fires?
Never been raced? Great, but have you ever missed a shift, or hit a pothole at speed? Do you run the engine through its rev range, or constantly lug it in the mistaken belief that keeping it under 3,000 RPM is good for it? How about short trips? Do you regularly subject the car to short trips where it never gets up to operating temperature?
Other lame copy in ads includes:
- No test drives. Really, as a seller you actually expect someone to plunk down tens of thousands of dollars without trying the product? Apply that approach to other consumer items to see how nuts it sounds. "No sir, I'm afraid you can't see the picture on the television until you pay me." Or "This True elliptical machine is very special, and costs two or three times as much as an 'ordinary' machine. You'll just have to take my word that it's awesome and functions perfectly."
- Serious enquiries only: What the heck does that even mean? How many people would spend the time contacting a seller about an item if there wasn't some level of interest? Any rational person selling a product should be happy to entertain any and all enquiries, as you can't identify a potential buyer until you ACTUALLY TALK TO THEM.
