You may need a vehicle, such as a small to medium sized van, to collect supplies from local cash and carries or wholesalers and possibly new and used machines from suppliers. The cost of the vehicle will depend on the size, make, model and specification. You could look at used vehicles as well as new ones. The older the vehicle the less it will cost to buy, but very old vehicles may not be economical to run and may project the wrong image for your business. An alternative to purchasing a new or nearly new vehicle outright would be to lease one.
Don't forget to tell your insurance company that the vehicle(s) will be driven for business purposes, possibly by several different drivers.
