Lots of good advice above, doesn't have to be a huge cost. I can't recommend Dalton ATVs in Wales highly enough, I bought my current quad from them, unseen in lockdown and they delivered it in a transport frame, had a running problem and they collected, fixed and returned it. 2WD semi-auto Honda, road legal, had loads of hours, cost £2650 but after nearly 4 years of us using it for probably an hour or two a day it is running sweet, only had oil changed and topped up, gear change getting a bit sticky so will need fixing soon but has been great value, if fairly flat ground you don't need 4WD and 2WD has less to go wrong. BTW my last quad was secondhand in 1998 for £1500 and lasted 22 years (used less than current one), sold it as a non runner on Ebay to a Polish bloke for £500, so 12.5 pence per day before servicing and fuel!
