I'll sell you one, currently parked in a garage in Finsbury Park.
1 Lady Owner
Good Runner
Cassette Radio (not stolen)
New chrome tipped pulse laser
Is that the one that was only driven on Sundays to church and back by the vicar? That's a fine machine, a steal for whatever you're selling it for. And I'm not just saying that because I'm getting a cut
OP, don't really know such locations by heart, I've seen the Adder being sold in a lot of systems though. High tech systems tend to have better choice in everything so if you filter for those in the gal map you should be able to find one. You may also consider going to Li Yong Rui space and grabbing one at a discount..
