I'd hope that most mid range rep stuff would be happy to do 50-90 in top gear regardless of there choice of fuel (I'm discounting the stupid stuff like the pious)

It's what was right about the Corkscrew at Alton Towers and wrong about all the new rides. The Corkscrew was bent by eye to a chalk mark on the floor and welded up in place to where it came, every joint was a rattler. New rides like Rita Queen of Speed are bent up on CNC presses that can allow for spring back and put up using laser levels. It goes quicker but is so smooth it's a yawn. -- Peter Hill Spamtrap reply domain as per NNTP-Posting-Host in header Can of worms - what every fisherman wants.

Meanwhile, back in the '70s, those were cars which were regarded as "old bangers". >> Perhaps you forgot that Conor also has a recent diesel Mondeo?

I really don't want to know whether you consider yourself "well-equipped" or not.

A > 1970s heap of shite that most people would regard as an old banger isn't. > In the eighties, my mother bought an S-Type Jaguar, wondering why it was so much cheaper than a Mk1/2 Jaguar, but needing the longer wheelbase for wedding dresses in the back. She then found out that, during the 70's they weren't as popular and were little more than scrap yard fodder, or hot rod donor until mid 80's even when in near mint condition. A 1960's S type Jaguar was considered a banger in the late 70's/early 80's so why shouldn't 30 year old design like the Capri be a classic now like the S-Type is. It is a phase. Used to be modern/banger/(Scrap/Classic). Now things go modern/banger/(scrappage/retro)/classic. The whole retro movement spans cars that were either never desirable when new, so rare and quirky, to the scruffy end of the older luxury market that eventually, as they are kept alive, will end up restored as genuine classics. -- Carl Robson Get cashback on your purchases Topcashback http://www.TopCashBack.co.uk/skraggy_uk/ref/index.htm Greasypalm http://www.greasypalm.co.uk/r/?l=1006553 |
