Just so you don't feel all alone, we're just reviving our car after 1 1/2 years in the underground car park. 100,000 km inspection with oil change, filters, change of break fluid etc.pp. Plus MOT. About 600 euros, they say, if they don't find anything unexpected. At least the tank is still 3/4 full. Was 1.05 euro per liter at the time.
And no, I can't do any of this myself. Wouldn't know where to do it.
Oh, yes, I need to do full wheel alignment, once I've swapped all the springy bits, and there's a 240000km inspection, too. Oil, filters, the lot.
Alignment I will outsource; the place where I'm likely to buy tires have done really good alignments of my old cars, so will let them do both, in concert. The rest looks like I'm doing it m'self.
