Used 2002 cadillac seville SLS for sale in Federal Way, WA

For sale, an excellent condition 2002 cadillac seville sls, I am the third owner I got this from a relative who got this from a friend who took good care of it (never really drove it) exterior is a 9/10 due to some light scuffing on the passenger side, not very noticable, Interior is a 9/10, EXCELLENT condition, has heated tan leather seats, dobly atmos and Bose sound system, mood lighting, cup holders, wheel controls, CD and Tape player, comfort settings for the seats and back heated seats (also has rear tinted windows) with rear cup holders. Trunk is super spacious and has a spare tire.
The engine is a very clean Northstar V8 32 valve that is VERY powerful and accelerates in about 7.25 seconds. and was completely redone last year and it hasn't been driven (except when we took it up from CA) oil changed, spark plugs redone actually recently, coolant put in, brakes replaced and battery replaced. Unfortunately the engine is leaking coolant into the oil which makes car throw up out of the exhaust, I did flush the radiator hose and put in a block seal which helped with previous overheating we think it's a blown or cracked head gasket or a bad intake manifold, I'm not really sure, if you know how to fix it this is a steal, it does run! Also has a short in the radio due to some disconnected wires, super easy fix just dont have time, Other than the engine problems this is a super nice car, and it has very low miles, only ~54000.
Please make a good offer.
