Why won't the back windows of my Vauxhall Astra go up all the way?
"The back windows of my Vauxhall Astra Twintop aren't going up, they stop about 3-inches from closing. Any advice?"
Might be the motors, might be the wiring harness. But if they are partially going up they might simply be sticking in their channels. Try lubricating the channels with silicone grease or Vaseline. If the channels are damaged, replace them (assuming you can get the parts).

Dealer won't pay to fix faulty roof on Astra Twintop
"I recently bought a Vauxhall Astra Twintop from a local dealer. The car was sold with a warranty that (the dealer said) covers the folding roof. Within a month of ownership, the folding roof mechanism failed. The warranty firm has told me that the roof is not covered and the dealer is refusing to pay for the repairs. What are my rights? "
Yes. Unless the dealer can prove that you did something that caused this problem, the dealer is responsible for this and remains responsible for it for six months from the sate of sale. See: Once he knows you know the rules he will probably pay up.

Which hard top convertible do you recommend?
"I am looking to buy a hard top convertible. The Volkswagen Eos is a bit big, so I am considering a three or four-year-old Renault Megane 1.6 or Vauxhall Astra 1.6/1.8. Have you come across any problems with the mechanics of the opening roofs with either of these models? Which one would you say is the better car?"
The Eos leaks like a sieve because the complexity of the roof requires a multiplicity of separate seals. I've heard of fewer problems with the Megane CC than with the Astra Twintop, and after a seemingly unfixable screen rail leak in its early years, complaints about the Focus CC have, er, dried up.

Best value engine size
"My bad back makes driving my current Honda S2000 painful and I now need more space, an auto box and ideally a metal folding roof. I rarely use the huge power available. Vauxhall Twin-top is cheapest but Design version rare, auto even more rare. I've also heard rumoured quality issues with roof mechanism. Eos has microscpic boot space when the roof is stowed and I hear some issues with leaking/rattling roof. BMW 320SE seems best option despite price ( budget £21k )- and tax/mpg costs seem reasonable. So what's the catch when buying BMW? Should I go for the 325 though? As auto 2-litre may seem sluggish."
The E93 3-Series is the best. Everything else has some sort of disadvantage in comparison.
