More than 1 in 4 car shoppers in Texas and Wyoming have committed to paying more than $1,000 a month, and experts say it is due to the high volume of large truck purchases in those states, according to a report by auto site Edmunds.

More than 1 in 5 shoppers in seven other states — Colorado, Kansas, Louisiana, Montana, Nebraska, North Dakota and Utah — are also forking over more than $1,000 for their vehicles each month.
