• Average new car sticker prices have risen 7.4 percent from $39,712 last June to $42,645 this June.

It's no secret that many cars aren't exactly affordable today, as new vehicles had an average sticker price of $42,645 in June. And for certain makes and models of cars, it doesn't stop there — hefty markups are still tormenting today's buyers.

Dealers tacked on an average of $4,000 in markups to vehicle Manufacturer's Suggested Retail Prices in June, bringing the average price up 8.5% to $46,265, according to automotive research firm iSeeCars.com.

But some vehicles are getting marked up by as much as 17 to 30%.

It's part of an affordability crisis that has car payments averaging more than $700 this year and more than 17% of consumers paying more than $1,000 a month, according to Edmunds. But even with increasing interest rates, rising monthly payments, and more car loan rejections, there's still strong demand for new vehicles.
