How reliable is your car being right now? If it appears in excellent condition and feels like it'll last you a good five plus years then go for it! However, if it hasn't been (for example, mine's been in the shop many more times this year than I'd like, and I've probably put upwards of $4000 into repairs/maintenance in the past year), then plan on replacing it with something that might actually be on the road when you need it.
