I will join the debate, the beat prices are very good in Japan but it cost at least a £1000 to get one over as previously shown hence you can pick a good 1991 in Japan for about £1000 hence landed on the road in the UK about £2000 would be the bottom line.
The good news is the Beat is a good cheap sports car to run, cheaper car tax and good fuel consumption.
Most Insurance companies reconise them and I get covered for around £200 a year, but I am old Fart (34)!!!
What you need to be is a little handy and do some of your own maintenance and source alternative parts!!!
Keep um good and clean and running well and they will be worth a few quid the older they get
