What to do?

Current situation: we have 3 cars atm, 1 of them is being used by my girlfriend the other 2 are only used by me.

Girlfriend's car:



My summer car:



My 'bad weather' car:





These are the cars I'm considering:
Lamborghini LP640 Coupé


Lamborghini LP640 Roadster


Upgrade Porsche 997 turbo to RUF turbo R

but it will feature the upcoming GT2 nose in stead of the Ruf nose:


Porsche 997 turbo cab




A few details:
- I live in Belgium which basically means we only have around 30-60 days max of truly excellent weather. So top of the

Murci Roadster is THE reason why I'm setting up this poll. Otherwise it would have been a done deal already (Gallardo

Spyder out, Murci LP940 Roadster in).
- The Porsche 997 turbo has a small advantage on the Murcielago Coupé: I can still put a child on the backseat there.
- I approx. know how the upcoming Ruf 997 turbo R will perform ... this car will be crazy when it comes down to

acceleration and torque (think Rt12 or better). I'm 1st on the list for this upgrade.
- The truck will stay because we will need it (little one on the way). But I'm struggling what to do with the other

two.

You can find my options in the poll, what would you do?
