Ok. Not really stretching budget but being more frugal about the spending.
So which used model is good. I've heard things like 997, 991 etc
991 is the latest model or shape.
How old are your kids? The seats in a 911 is not what I will call 'comfortable' for larger kids and or adults. For a quick trip down to the mall or so its fine but not for extended driving.
When buying a Porsche, and or similar, the purchase price is usually the least of your worries. Maintenance is a big one especially things like tires. Can easily set you back anything from R20,000 to R35,000 per set depending on what you buy. Porsche does have a tire program but the prices for the right tires are still high.
Insurance is another thing.
Check the Autotrader or check their website (Porsche) for 2nd hand vehicles. There are some very good ones with sub 10,000 kilometers on the clock to be had for a good price.
