Pay cash. But having just purchased a new van, YESTERDAY, I cant pay cash so I took out a loan. This is my second car from this dealer and after crunching the numbers, I feel that I was treated fairly vs. the quotes from other dealers that I have not bought from. Chek out Kelly Blue book and Endmonds for pricing and "true" car values. I spent the last few weeks comparing and pricing vehicles, crunching numbers with the online calculators etc. go to the dealer informed and prepared. Look at AutoTrader to see comparable vehicle pricing too.
Exhausting but worth it.
