Are you UK based?..... I wasn't aware that having your vehicle registered as 'historic' carried any restriction on use??
Assuming this is aimed at me. Australia, the rules are different for each state but for where I live the rules are
The car must be over 30 years of age.
You must be a member of a club affiliated with the Council of ACT Motor Clubs
Use is restricted to 2000miles or 3000km per year and must be for one of these three
1. Events organised or approved by clubs affiliated with the Council of ACT Motor Clubs;
2. Occasional test runs of up to a 40km radius; and,
3. Specific occasions not related to club use such as weddings when permission is first obtained from the appropriate club.
Registration then costs $120 per yer compared to about $1000. So the guy I met was doing an occasional test drive every week of each car however I have read somewhere in the past that the car can't be parked in a public car park or shopping centre if on historic registration. A test run can not be combined with commuting or shopping.
To be honest whether it's cars, houses or whatever I can't remember buying any of them for 'investment' rather than 'I really want that'!! :-)
I agree 100%, Only ever bought three houses but each one has been what I want and where I want based on what I can afford rather than what I thought was the best investment. The only difference between houses and other purchases is I am happy to borrow money from a bank for a house. Cars I always expect to lose money on, same as guitars but I think I could sell one for what I paid for it 30 years ago.
