What is the literal meaning of 以 in 以 ... 來 pattern like in the following sentence: 以我的情況來看. What is the syntactic role of this word (verb, particle, etc)?
[以 ... 來 + (v)] = [with/ according to/ base on ... to + (v)]
[以]我的情況[來]看 = [to] assess it [base on/ according to] my situation
[以]我的想法[來]說 = [to] judge it [with/ according to] my thinking
[以]他的指示[來]做標準 = [to] make standards [according to/ with] his instruction
When you can replace 以 with 從 in your sentence, 以 means 'from'
When you can replace 以 with 用 in your sentence, 以 means 'with'
When you can replace 以 with 跟據 in your sentence, 以 means 'according to'
Your 'sentence' is a phrase. On its own doesn't really tell us much. It needs a bit more.
In my present situation, I don't think I will be able to go to Zhejiang tomorrow.
In my present economic situation, I don't think I can afford to buy this S600 Mercedes.
How you translate 以 will always depend on the context. There are no hard and fast rules. Oftentimes it won't get translated.
PS： 我把車輛賣掉了 does not mean "I took the car and sold it"
我把那輛車賣掉了 = 我卖掉了那辆车。= I sold that car.
If you ask a Chinese friend to translate "I sold that car.", he or she will probably tell you:
我把那辆车卖掉了。Chinese people prefer this word order I find. Why? 不知道！
Quite why Chinese uses 把 to achieve a different syntax I don't know, but this 把 or 将 or sometimes 给 don't contribute any meaning, they just allow for a different word order.
