Do Leaseplan buy cars or take "trade ins" on Company Lease cars

Hi
I have been offered a new job that comes with a Company car, I had thought I would be sent to a garage to buy with Company cheque and could negotiate a deal on them to buy/take a trade in on my old car. It turns out though the car will be purchased through Leaseplan. How can I offload my old car. For personal reasons I really do not want to go the private sale route (I live on my own and would be nervous going out in the car with total strangers!) As I have not yet started in the job I am reluctant to ask too many questions but does anyone know do leaseplan "buy" or trade in cars giving me back a cheque for its value

Tks

No they dont. Key is in the name. Leasing is all they do.

If you are nervous about selling your car yourself, could you enlist the help of family or friends? Failing that, a number of garages will buy the car from you for cash. You will get less that way, but it will eliminate the hassle and dealing with strangers.
