It's rare that someone would pay more than $5500 at this time for an excellent 1990 560 SEC , But more rare that this car won't need $$$$ worth of repairs and up keep soon ,go back in about 3 months ,the price will be a lot lower if it's still there ,and if it's gone ,then you saved yourself a lot of $$$$,, find out if the A/C blows cold , if the car has front end shimmy ,if there is rust in the usual spots , if the chain guides have been changed,if the compression is good and make sure the rear suspension is good, also if you buy this car you will have 2 money pits. I also have a 420 SEL, I've had it for 10 years, if you can do the labor for repairs yourself ,these are great cars to own.
