Buying Guide 1986.5 - 1993 Mk3 model
This is to help people who are looking to buy a MKIII Supra. Toyota cars are expensive to fix when things go terribly wrong. But as you browse the web you will be able to get information on fixing them cheaper or by yourself.
Service History

No Service History - Bad, No record of mileage. Car Should be cheap. Ask for any receipts and old MOT's.
Part Service History - Better than none, but above still applies.
Full Service History (But not by Toyota) - Very Good.
Full Service History (Toyota) - Excellent. When Toyota have your car, they make sure anything slightly worn, is changed, if not its noted on the report.

Always try and obtain as much information as possible.

Exterior

Rust Spots - Supras are not known for rusting. I Have only ever seen one Supra with bad Rust. But I've seen a couple that are just starting. Luckily for me, my car has been very well looked after regarding the outside. Check rear spoiler, the middle mount appears to attract rust. Look around the door locks and seals. Check the inside of the rear wheel arches, and rear wheel arch outer edges. Check around the front wheel arch outer edges. Front side skirts are not a very good design, they are attached by plastic plugs that push into the sill, BUT the plugs seat on a steel strip and this is constantly getting wet. The result is that the steel strip seems to rust quite a lot. (Pushes front side skirt away from sill). To fix this use clear silicon sealant on the top of  the side skirt, this will stop any water from above running down.

Wheels - Check condition of the wheel itself as well as the tyres. Are the tyres shot ? If so they can cost anything from £50 - £120 a tyre. The wheels, if they are scuffed can spoil the overall look of the car. If the tyres and wheels are in a bad condition, that says to me that the last owner was not a careful owner. Check the inner edge of the rear wheels, if they are badly worn, then it suggests that the rear bushes are worn.

Look at anything that is a different colour from the car body paint, check for overspray and badly painted areas. See if the Supra has original paint. NO ONE and I mean NO ONE can match the quality of the original painting, unless the car is stripped to the bare shell and sprayed again from the bare shell up. A good place look is around the windows on the black strip.

Windows / Lights - Check all the lights and windows for markings. Are they all the same ? If not, could be a broken window had to be replaced. (Car theft, Accident etc.)

Interior
Leather seats look great, but check the driver seat side support, this is known to wear, can cost up to £100 to refurbish. Check the pedals for wear, if the pedals are worn and the clocks says less than 70,000, then you probably looking at a clocked Supra. My had  99,000 miles on when I bought it, and they were not even scuffed. Check all the electric's and see if they are working correctly. Watch that oil gauge, I know of a couple of Supras including mine that had faulty gauges.
Engine
Unscrew the oil filler cap, examine the oil condition. Is there any sign of white/gray cream in the top of the cap, if so probably a Head Gasket leak or a fault with the valve seals. Pull the Dip Stick out, is the oil clean, brown or black. Back oil suggests that the oil has not been changed for some time. On Turbo Supras check the connections on the Turbo Unit. Check to see that they are all in good condition, check the heat shields around the Turbo. If these look like they have been tampered with, it suggests that the turbo has been replaced. Generally look for all types of leaks (OIL / WATER). Look for scratches around the Suspension tops, these are caused when the Engine is taken out!.
Test Drive
Check the General sound of the Engine. When a Supra ticks over, you should not be able to hear the sound of the engine inside the car. On Turbo`s the Turbo unit does make a whistling noise on acceleration, but this should not be excessive. If the noise is excessive then it indicates that the Turbo bearings have worn.
Before you BUY
Please check on the Owner Registration document ALL the details. Check the number of Owners, Address & Name of Previous owner. If not sure then don't buy. Don't believe what the seller tells you!. Check that the Chassis number and Engine Number check out okay and match those on the car.
