Hi Spandex
I have owned a Mk1, 2 and now a Mk3 ...... all of them fabulous cars. Mk3 is the best. Driving them as a main car for 10.5 years and wouldn't want to drive any other limo.
Pas pumps leak on the Mk1 and 2, exhausts blow at the flanges eventually but fixing is well documented here.
The pas pump leaks onto the alternator and that's expensive, but again should last 150,000 miles at least
Batteries last for years and years, wiper blades best bought from Lexus / Toyota coz they last a lot longer than other brands.
The Mk3 battery is really only replaceable by Toyota coz of it's shape and the slot ...... and it's only £70 or so ( cheaper than halfords etc )
The big expense on the Mk1 I had was the front suspension stuff, really only worth getting Lexus parts, last for 150,000 miles min.
Stop lamp bulbs last at least 16 years and cost a couple of squid and 2 mins to change provided you read the manual.
The Mk3 seeds a little better with fuel consumption and the wisdom that I read on here is that the car runs more economically when the gearbox is in PWR mode.
Original Dunlop tyres are no longer made but Falken, said to be made by Dunlop seem a great substitute.
All in all, fabulous and non-destructable cars where the power train will outlast everything else on the car, and on the road forever.
Just superb motoring whichever you choose.
