Pete Rose owes more than $1 MILLION to the IRS ... but you wouldn't know it by looking at his car -- 'cause the ex-MLB star is still pushing a very expensive Rolls-Royce!
TMZ Sports has obtained pics of Rose's Rolls-Royce Wraith -- a car that usually costs about $300,000!
And to make sure people know it's HIS car, Pete got a custom license plate bearing his nickname, "Hit King."
Remember, Rose has admitted in court docs he fell WAY behind in federal taxes and is working to repay Uncle Sam the 7-figure debt he's racked up over the years.
