There are many variables to consider at present. The main factor being your disposable income – i.e. money left after paying home bills and food. For some an extra £400 a month on bills is not that painful, to others it is a fortune. Deciding on when to change your car is, again, a decision based on several factors.
One of my neighbours prioritises a new motorcycle every two years over decorating and maintaining the family home to a reasonable standard (in my view). Most people on the forum love cars and motoring, so a car might be a higher priority compared with Joe public. I agree that the “new” car feel soon wears off. Linas says ,“Not being able to predict and calculate depreciation is what impact me the most.” This would only apply if you changed your car regularly. Depreciation significantly reduces the longer you keep a vehicle. Many on here own older Lexus cars and can afford to run them due to good reliability. Would I consider running a 1998 4 litre Jag – no way! Second hand prices, at present, are ridiculous as far as I am concerned but if your car is written off you have no choice but to buy another. I agree, with Spock99 (Andrew), when a car becomes unreliable then that would be the time to change. In the nearly 7 years I have owned my LS400 it has not depreciated. Yes, I have had expense on consumables, but that is with any car.
I will probably stick with my present cars.
I agree with Linas and Malc, that the volatility in the car market is uncertain right now but it will settle down in the future. The big uncertainty is deciding on the fuel to run your next purchase. - diesel/petrol/hybrid/plug-in hybrid/electric ?
Have I opened another can of worms?
