l need one for my limo business

Depends on the condition and mileage.

The ugly square one can be bought for peanuts, there is one on ebay.

you can grab one that runs for about 4000.00 usd,, but they are going to have high mile if they were in service,,,

Heres a trick, there are companies that deal in funeral cars
and they have 30,000 miles on a 15 year old car,, remove the center seat and spend a grand designing it yourself. l was luck and was able to flip the center seat backwards on a caddy and it worked great,,,
