Ok so thank you all for the responses up to this point.

First and foremost, this bike is indeed the LeMans model. I thought it was a 700 because the bike shop had identified this as a Centurion 700 on my service slip. I was foolish enough to not take a closer look in the first place.

Secondly, I just got the bike back from it's service. Spent upwards of $150 (closer to double the estimated value) in servicing this bike which in my opinion, was too much. Part of what ran up the cost was the servicer advising to put on two new tires. The original tires were deflated and had little tread, but probably could have still been ridden on. It was $25 per tire. I do regret not keeping the original tires because they certainly were cool and would have kept the bike all original.

It is raining out today, so I only had a chance to ride up and down my small street. The position of these older road bikes is very low, and some could say uncomfortable. But it will grow on me, especially for the type of riding that I will be doing (campus and commuting).

So I took some better quality pictures and will upload them for more help in identifying the year of this Centurion.

A few things I want to note:
- The components have the name, SunTour, on them. Was this Centurion's in-house component brand, or another Japanese bike company?
- I noticed Sakae Randnner's name on the handlebars, could this be the Centurion LeMans Sakae Randnner edition?
- The very last photo is of the serial number, N1G0561. Anyone know how to read this serial number and put it to a date of manufacture, etc.?
- Also what is the Japan Cat Eye Model 300? It is on the end of both handlebars.
- Still kept the original grip, which I am glad I did. The bike shop said it would run about $35-40 for new grip, but I like the look and feel of keeping the bike original.
- Because I am not familiar with Centurions, is this the original seat that came with the LeMans model? I am not sure if the person who I inherited the bike from had switched saddles at some point...
