I don't pay interest. Just bought a 2010 Dodge minivan with options I didn't even know they made with 75,000miles, no rust as it went to the Southwest every winter. 3 TVs 4.0 litre 6 speed power everything & tons of storage under the floor. Every option available for $4000. Very comfortable to get into & drives like new. I had diesel Rabbts back in the day & am 6'4". They were comfortable & got 55 mpg. I have 2 low milage diesel trucks also with the last year before the computer. IMHO a computer on a car is not a good thing as I had a mouse family move into my plow truck, peed on the computer & the insurance co totalled it. 20 years from now who's going to service the computer?
