Update 8:15 a.m.:

The tax man has cometh and sometimes even he can make a mistake.

Greenwich resident Frank Yantorno was rather surprised to find the 1955 Ford Fairlane he had owned for years was listed in the Top 20 car assessments for 2011, as released by the Greenwich Tax Assessor's office. What was even more surprising to him is that he doesn't even own the car anymore.

According to the list released by the assessor's office, Yantorno's 2-door sedan was assessed at $374,100.

"I sold that car last fall and turned in the plates. I should find the guy I sold it to to get the other $320,000 or whatever, he owes me," Yantorno quipped.

Well, it turns out there was a clerical error in the information provided to Greenwich Patch.

According to Personal Property Appraiser Ali Karimi, "there was a clerical error in our office when values were entered into our database. The mistake was caught prior to the article you wrote, but the "Top Twenty" list (provided to Patch) was derived from our pre-corrected data."

The corrected assessment on the Ford is $500, because Yantorno had the car registered with Early American & Antique plates, Karimi said.

Cars registered in Connecticut with the Early American & Antique plates must be at least 20 years old and the maximum assessment on the cars is $500.

Original story, Feb. 8:

Seeing Ferrari's, Rolls Royces, Maybachs, Bentleys on the roads of Greenwich are common.

So it's not a surprise that when it comes to perusing the Greenwich motor vehicle tax assessments, those are the models making the top 20 spots on the list.

According to the 2011 tax assessment list released by the Greenwich Tax Assessor's office, there are 54,092 vehicles in town with a total net assessment of $744,522,820.

And at the top of the most expensive list is the 2003 Ferrari Enzo Coupe. There are 2 in town — one is owned by designer Tommy Hilfiger, the other by William S. Pepe. Each car has an assessed value of $633,360. Greenwich Personal Property Appraiser Ali Karimi said each year the assessed value fluctuates, depending upon market conditions. He said that when the markets were high, the assessment of the Enzo was more than $900,000.

According to Motor Trend magazine, only 399 of the 660-plus-horsepower Ferrari Enzo's were made in 2003. Top speed is 200-plus mph. Back in 2003, the pricetag was a cool $650,000.

The mid-engine 2010 Ferrari 458 Italia that came with 562 horsepower, according to Automobile magazine, is proudly owned by 3 Greenwich residents — Carlos M. Hernandez, Putnam Leasing Co. LLC, and Pepe. The assessment on that model is $200,690.

Karimi said to calculate the value of a car, divide the assessed value by .7. So Hilfiger's Enzo Ferrari could fetch a handsome $904,800 on the open market.
