You want to know why Ling is reluctant to discuss much on the phone?

There are several reasons.

She is very busy and the phone takes lots of time.

Also, because cars are worth thousands of pounds, Ling likes to keep things in writing, so everyone has good records of what was discussed.

She may also need to research the exact answer, and it's hard to do that while on the phone.

Please email or use webchat or LINGO.
