There's zilch in the Gospels that says being wealthy is good and a lot that says it's dangerous for your soul.
This is almost certainly neither the thread nor forum to dive deeply into that, but I don't agree with that assertion.
Being wealthy is neither here nor there, Biblically,
as long as your trust isn't in your wealth. And as long as you're not, to borrow some phrasing Paul uses a lot, "greedy for dishonest gain" - which is applicable at
whatever wealth you might be at. I think you see that sentiment pretty clearly from Jesus as well, when He clears out the temple courtyards calling the vendors and moneychangers a "den of thieves" as well, and it shows in his interactions with some of the tax collectors also - they were pretty much the case study in "dishonest gain."
There's also a consistent thread of, "From those whom much is given, much is expected," and we certainly try to live that out in our lives as we can.
I don't think owning a reliable car to get around is a huge problem, though I grant I've got a pretty flexible set of definitions for reliable. I do think owning a high end luxury car, because you deserve it, is pretty questionable from a Biblical perspective. If someone wants to drive a $200 car, and it gets them around fine, great! Have a ball, I've had more fun with my $200 cars than with the expensive ones (autocrossing an 1800 lb, 50hp Daihatsu on a wet morning is
hysterically fun when the Mustangs can't hook up the power on the course).
