advice please

[SSBUB]

Need a little advice guys, - i posted this in the ls1 forum and would also like your opinion

Heres the situation: I am a mobile personal trainer and have a requirement for a largish car for my stuff (Weights etc). I own a 2000 VX SS (lets pretend this is a BA xr8 lol) which has become my weekender. We also own a 2001 3 door astra which is the misses. NOW:
I bought a 91 model toyota surf off my old man for 8k, which serves me well for business purposes. The old man wants 8k for it, and he gave us the car in advance. We are going to sell the astra to give him the $$. Now heres my conundrem.
Should i sell the SS instead? It only gets weekend use by me and my misses would be the only driver of it to work - which is about a 15km round trip every day in a safe place. However if she lands this new job she will be taking the bus to the city and leaving the SS at a public transport carpark

Now my options:
1) just sell the Astra as originally planned, keep the SS and just let natural depreciation take its course. I owe 8k on the SS still.

2) Sell the SS, keep the astra for the misses, pay off the debt owed on it, pay off the old man for his surf AND get a bike. I have always wanted a bike but to be truthful, am a little nervous as to the whole 'no metal surrounding me' thing and the 'death may be inimint' thing. However i was thinking i would like either a CBR250RR or a GPX250 or ZZR250: All learner bikes. The purpose of the bike is to simply have a fun toy for the weekend. It wouldnt be a toy in the sense of being a revhead, but rather something to enjoy as I have never ridden before. I am not unhappy with the SS but i want, neh need, to replace 1 toy with another.

Any advice?
What would you do? As i said earlier, pro-ford answers to selling the SS is not what im after, so lets pretend it is yourself with an xr8 or something
