I sold cars for two years...quite an education...
I sold new toyotas and used cars...usually cars we took on trade...at the time, Toyota was HOT...we routinely added our own sticker to the MSRP and then added a $500-$700 "protection package" and anywhere from $995-$5000 "market adjustment" price to the car/truck. This gave us a huge amount of profit potential and "room to dicker" with people coming in. The protection package was added on by the lot kid who washed the car...a bit of spray on scotchguard and a can of undercoating was the primary adds. Oh yeah, a Protective film, that was sprayed on the car then wiped off...nothing more than a "detailer spray" i think.
Most salesmen, i was, are on commision. Of course you want to sell the car for the highest dollar amount you can get. Everyone talks about "repeat customers" and "repeat sales" but for the most part, its just the here and now. Car salesmen frequently change dealerships so the repeat sales arent usually a huge deal to them.
One gimmick we used still makes me laugh. Toyotas in solid black were hard to find. We told the customers, commonly called "ups", that black was a ceremonial color in Japan. In honor of that, Toyota only producted a few black cars...and there were fully optioned in honor of the status Japan felt toward them...i even got to where i could say that with a straight face and never had a customer call me on it...
Anyway..my take is...
New Car Dealer: Obviously new cars have advantages, mostly warranties and no issues with prior maintenance. Used cars usually have some sort fo warranty from there...depending on the dealer, alot of times there are useless...read the fine print...the dealership (stealership) i worked for basically offered a warranty that gave you @0% discount on parts and labor..hardly a deal.
Used Car Dealers: Virtually same as new car, however, many can be fly by nite. At least at a dealership, they are usually in business long enough that, if you have a complaint, they are still there....this is iffy with some used car dealers.
Private Party: your best deal price wise but with risks. The car maybe stolen. Check the title closely, is it in the same name as the person who is selling it? Does the seller provide a home phone number or is it just a cell phone? Can you meet the seller at his home or does he just want to meet in the "sumpermarket parking lot"? Also, if you buy the car and find the engine is full of STP to keep it from burning oil...you have little recourse...of course you can sue..which you might or might not win...but that is little good if the car is crap...
Good Luck...
