@ Arcee - nice choice, I've never seen that Jaguar before... looks like an E-type crossed with a Batmobile
@ Minerva - Great choice, that Opel... the continental version of our Vauxhall VX220 over here. Made by Lotus on their Elise wheelbase and chassis, and it drives better than the Lotus which costs quite a lot more
@ Ratchet - I see your Schwartz is as big as mine
@ Ramjet - looks like something Homer would design in that episode of Simpsons where he gets to make a car for his brother
Here's my latest choice for an Alt mode - the BMW Gina concept car... I saw this today and was open mouthed for ages whilst I read about it

. I would normally only post one pic, but one doesn't do this car justice - a wee snippet of info about how it works is also included. This really is a weird, but awesome car (and they'll probably never make it apart from for a few movie shots or something

). Car fans will spot it's based on the Z4 shape and its hinted that the next Z4 could be aiming for similar looks (without the amazing moving skin...)
"As fabric roofs for convertibles fall out of favour, BMW has discovered what to do with all that left over material; cover the rest of the car in it.
The GINA Light Visionary Model is a two seat roadster with a textile cover that resists water and extremes of temperature stretched across a moveable metal framework for an almost seamless outer body.
The car's real sci-fi trick however is its ability to morph; changing shape like the liquid metal robot in Terminator 2 depending on what is required of it. Metal wires pin the hi-tech fabric to the body panels and electro-hydraulics attached to them can stretch it in different directions.
At the front of the car the traditional BMW twin headlights remain hidden until required, at which point the fabric is peeled open like a pair of eyelids. Rear lights are invisible under the fabric until lit. The familiar kidney grille can be altered to increase airflow, the side panels stretching apart and at the same time creating sharp creases along the front wings.
BMW has also done away with the traditional bonnet opening, instead replacing it with a horizontal split in the fabric that runs along the mid-line of the front panel and gapes open like a surgical incision."
(sorry about it making you scroll to the right - I've tried editing the post, but nothing sorts it
