I was hoping it would add a little to her value.
She hasn't been started since December. I've checked the coolant level (it seems okay) and she still has plenty of oil. Is there anything else I should check before I turn the key, or anything I should be looking out for?
That is a good price for a showroom valet, it is well worth getting it done, it will add to the selling price and make it fare easier to sell. It will smell nice too
I would put it into third gear take the handbrake off and rock her backwards and forwards to turn the engine over just to make sure that nothing is "stuck" inside.
You may also find that the rear brakes have seized onto the discs, assuming the handbrake has been left on (Kimshros has the same problem with Della, her TF which had been unused for 6 weeks)
You may also find the battery will be flat too, unless it has been on charge since she went into hibernation?? The alarm system take a lot out of the battery whilst the car is standing, mine went flat in about a month and it was a new battery.
Hope this all helps
