It's simply the law of supply and demand, there are loads more MGBs and Midgets about than there are Dolomites, even though all Dolomites share a disc, they are not a frequent swap item, so no supplier is going to order 500 sets at a time to get the cost down. I doubt even Rimmers keep more than half a dozen pairs on the shelf. Because they have to pay more for small quantities, they pass this on to us (no doubt, with interest)

I've often thought about getting a 2000 again, my first car and it'll take me right back to just passing my test and being 17 and two weeks (couldn't wait to get that driving license) all over again, which is usually what stops me!
