I have an Aero 2002 MK i
When i brought the car from Mole Valley (Aug 2006) I was told that i could have a hard top, so I asked them to order one. About 3 weeks later they told me that you could only have one for a 2003 car or later so I was out of luck, a little anoying I may have waited to find a 2003 car if I knew befor I brought one. I think as the 2003 is also a MKi the diffrence is how the hood fits to the windscreen mine has a big bit of Ash attached to the hood with 2 metal spikes that clamp through the metal bar on the top of the windscreen I think the 2003 has some diffrent type of fitting. I have just asked Mole Valley to tell me if the screen / hood can be changed to alow a hard top I am waiting for there reply. I drive the car a few times every week in all weather and the last few weeks I have got a little few up of having a wet arm where rain drips through the door/ hood join.
