If you have somewhere to store them properly out of the weather year around, then get as many cars as you want.
If you have to leave them outside, that's not a great thing as they start to deteriorate faster that way.
I have 9 cars and I do not even have a garage at home.
I have to rent storage and that is expensive.
Plus The City of Toronto charges 134.00 each car to register each year on your birthday plus the cost of your drivers licence renewal. That is not a very nice birthday present for me with 9 to do.
Unless you can afford it, having lots isn't a good idea either.
They usually could always use something or could use improvements
and that is hard with lots of cars.
Sometimes I wish I just had a couple and less headaches but I have a hard time getting rid of any of them. The ones I have sold sometimes still bother me.
Yep, we all have the same problem... we love our cars !!!
Maybe I (we all) need some kind of therapy.
