关于菜鸟在CL挑二手车:
目的少花钱,车况尽量好,从维护费用低来省钱,而不是保值
价格($5k-7k,太便宜了没好货,太贵了不值得):基本对你要的车型的行情有个了解
,不要太贪心,看查不多就联系卖家,准备看车
具体到车:美国车,一般都是V6以上的才可能买的到,V6 taurus, impala, sable,还
有dodge, pantiac,V8的crown vic之类的.同级别,同年代,历程的比一个dfbb少好几
千块,够你烧好几年87号油的。加上本来就便宜,再折旧也折不了多少
good
里程75K以下(开到90k就赶紧卖掉,因为一般到100k要花$1k保养)
年代尽量新7-8年以内的
google没有设计缺陷(像什么leakage,断轴,杀不住等bad design/recall,敬而远
之)
保养好正常service record一堆(看车时,如果有一个部分反复修好几遍的,说明也许
问题很严重,还没找到问题)

刚刚完成2012 Nissan Altima的60k miles维护,想问几个问题。
Dealer要求换cvt fluid,我没有换,有这个必要吗?正常使用,从没有拉过拖车。
Oil coolant leakage

是不是要更换oil coolant和rear shock?
另外,Nissan车是不是小毛病太多了?也许我以后换二田。

来自主题: Living版 - 屋顶渗水?
It can be roof leakage or leakage from the pipes in the attic. The easiest
way is to go to the attic and find the source of the water right above these
two spots. Then decide which types of people to call in, or you do it
yourself.
I had a similar problem as yours. Eventually I found out that it is because
the roof had some missing shingles. I bought some and fixed it myself.
Anyway, you have to get it fixed as soon as possible before it gets much
worse.

If so, I agree with 老树临风 to check if there is any leakage around the
mold area. If you find such leakage, get it sealed as quick as possible. If
not, it could be that there is some broken pipe inside the wall or water
coming down inside the wall from some problem area above.

If no leakage, most likely you have a problem with compressor in the

Suggestion: get a service guy to take a look. Ask him to test freon

and try to use a hard start kit to start your compressor.
