    New Potential Seville Owner Seeking Advice

    I live in southeastern Idaho and I am looking at a 2003 SLS with ~74000 miles. This car is a local trade in and to the best of my ability to check things out everything seems to work. The battery was dead when I first looked at this car and the dealer has installed a new battery. I have looked under this car several times and can see no evidence of any oil leakage. I have made an offer of $7000 if the dealer will flush the radiator (with factory recommended coolant) and install 4 new tires. He is willing to do this to move the car. My question is how likely am I to be purchasing lots of future repairs. This forum has been helpful. I get the sense from other threads that these cars will eventually require costly repairs (statements like "bring money"). I like this car and will use it as a daily driver mostly highway 35 miles to and from work. Is there any thing else I should consider looking at this car? Thanks in advance for your views. Keep up the great work with this forum

    Check coolant level, test drive the snot out of it, let it cool down and check level again.

    IF you do the hard test drive, be very careful when you remove that coolant reservoir cap: that system will have 18 psi on it and all hell will break loose if you open it hot. NEVER open a Northstar cooling system hot or if you can feel pressure in the top radiator hose. If you can see orange coolant through the top of the translucent section of the reservoir, you're OK.

    Have a GM dealer service writer run the car's VIN through the GM VIS database - this will give you any recall, warranty, and some GM service work performed on that car. You run the VIN through the "VIN to RPO converter" thread at the top of the main Seville page. This will give you all the Regular Production Options built into that car.

    74,000 miles is right at the national average annual mileage driven - 12,500. That mileage is also not a lot for a Northstar engine. The 2003 represents the final development in the FWD Seville, so it has all the latest updates, including the roller cam follower engine. If the car looks good, with no obvious defects (interior and body), and starts and runs quietly and strongly, it's worth a buy. You'll get about 26+ mpg, highway, on 87 octane, 20 near suburban, and 12 - 15 in the city. The engine takes exactly 7.5 quarts of 5W-30 oil (with filter) of whatever type floats your boat.

    Is this a GM dealer? They should know better, but if not, be sure that it has a 79 series (vented) battery (under the back seat).

    Perhaps there is a lemon law of sorts to fall back on in your state. Some states give you 30 days by law to return a vehicle to a liciensed dealer if it ends up having unforseen major repairs if that dealer doesn't correct the issue. I think you are getting it for real good price. The only terrible problems would be of course the headgasket or a trans problem.
